• This repository is mainly used as part of my online free coaching. However, it will be beneficial for others.
• The repository contains mini-editorials/notes written by my trainees for some problems in several OJs (UVA, SPOJ, LiveArchive, Timus, etc).
• The same also for the IOI and OI problems (CEOI, Baltic, Balkan, APIO, etc).
• I searched and organized many of web official editorials/solutions for IOI/OI to make it easier for my trainees.
• The content will grow up more by time.

For more details, read and explore the repository

Have fun :)
